Final Fantasy Finest Box is a promotional compilation set containing the soundtracks from Final Fantasy IV, Final Fantasy V and Final Fantasy VI. The Final Fantasy IV disc includes several tracks not included in the original OST. The other two games' discs include all the same tracks as their respectiveOSTs. The music differs somewhat from the originals due to arrangement by the TOSE team and sound programming to meet the GBA's specifications.

This limited edition was free to 5,000 people who purchased all three Game Boy Advance games and sent proof of their purchase. This was only offered in Japan. This set has never been sold in retail. The discs come in a large, 6-disc holder and the set includes a booklet titled "Amano Yoshitaka Kajuu - Yoshitaka Amano Works 1991-2006" containing Amano artwork from all three games.
